A method for processing GPS route data of a vehicle is proposed, in which the GPS route data are used for the route guidance of the vehicle along a route (), wherein vehicle positions and an offroad position information or an onroad position information are generated as route data, wherein a vehicle position calculation function for route guidance of the vehicle is used, if erroneous vehicle positions are generated from the GPS route data. Furthermore, a control device for carrying out a method is proposed.

Disclosed is a method for determining a position of a motor vehicle by means of a location device of the motor vehicle. First, a first position (x) related to an installation point of the location device in the motor vehicle is determined. In order to determine a position suitable for controlling the motor vehicle, with reference to the said first position (x) a second position (x) related to a center of gravity of the vehicle is determined, in that the first position (x) is offset by a distance (a) between the said installation point of the location device and the center of gravity of the vehicle.

A method of operating a clutch serving as a shift element and/or starting clutch of a drive train. During engagement, the clutch will be filled by a fast filling up to a defined minimum pressure. The fast filling is at least subdivided into two phases comprising a basic filling phase and an extension and/or a cutout phase. At the end of the basic filling phase, the actual clutch pressure is measured, and then, when the actual clutch pressure is equal to or larger than the minimum pressure, the extension and/or cutout phase is activated immediately following the basic filling phase. When the actual clutch pressure is lower than the minimum pressure, activation of the extension and/or the cutout phase is at least delayed by a pressure holding phase and, if necessary, by a pressure surplus phase.
